f CAN-CAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 227,468, dated May 11, 1880.

Application filed October 21, 1879.

I To all whom t may concern:

Be it known that we, JOSEPH ADAMS and EDWARD RENNEBURG, both ot' the city of Baltimore, in the State of Maryland, have invented certain Improvements in Gan-Capping Machines, of which the following is a specification; and we do hereby declare that in the same is contained a full, clear, and exact description of our said invention, reference being made to the accompanying drawings, and to the letters of reference marked thereon.

The invention relates to a machine in which a can or series of cans bearing loose-caps are placed in a tray resting on a sliding table and caused to pass under arevolving hollow cylindrical soldering' iron or irons, each iron having a weighted presser-rod passing through the center thereof, the iron or irons being heated by gas-jets, and made vertically adzo justable to admit ofthe passage'of the can or cans to and from the soldering devices, and

also adjustable in a direction admitting of achange in the distance between the centers of the soldering-irons, whereby they may be used in capping cans varying in diameter.

The invention consists in certain details of construction in the various parts of the machine, as more particularly hereinafter setforth.

In the accompanying drawings, Figure l is are placed a series of shaft-bearings, O O,

which iit neatly therein. The shaft-bearings O'have holes their entire length, receiving the vertical shafts D D of the soldering-irons E.

Thelower ends of the bearings C are threaded, and by means of the upper enlargements or heads of the bearings, the washers b, and nuts c, the bearings are clamped at the proper distances apart between the framing-irons B.

The shafts D consist of tubes, and are provided with sheaves d at their upper ends. Between tlie sheaves and the upper parts ot' the bearings C is a slotted bar, F, which aids in steadying the said bearings and the shafts.

At the lower end of each shaft is a sleeve, G, having a iiange or collar, e. is held 1o the-shaft by means of a set-screw, h. The collar e is of the same diameter as the interior ot' thehollow cylindrical soldering-iron and rests therein, the connection between the two parts being effected by means of the setscrews It, which pass through slots cut in the body of the soldering-iron. A presser-rod, m, having a weight, m', at its upper end, passes through the center of each shaft D. the lower end of the rod being adapted to rest upon the top of the can-cap. h

'At the center of the slotted bar F is a link, a, connecting with a lever, o, having a fulcrum at o', which lever, when depressed, causes the entire series of soldering devices to he raised. A line of shafting, H, is arranged in suitable relation to the soldering devices, and provided with pulleys and belts for driving the same. Motion is given to the shafting H by means of a belt leading from the wheel I, which may have any suitable location.

K is a sliding table, on which a tray, L, may be placed, if required. The cans M may be placed on the tray or directly on the sliding table. Y I

A gas-pipe, N, is placed in some convenient position and provided with branches a,'one of which leads to near the upper part of the periphery of each soldering-iron.

The operation of the machine is as follows: The soldering-irons having been placed the proper distance apart between centers to suit the diameter of the cans to be capped, the branch gaspipes are then lighted, the gas-jets leading as above stated. The soldering-irons are then put in motion or caused to revolve. A series of lled cans, bearing loose caps and rings of solder, are then prepared for the action of the machine, being either placed directlyon the sliding table or in the tray. The lever ois then depressed, whereupon the entire series of soldering devices and presserrods are raised sufciently to allow the cans The sleeve G IOO to go under. The cans being put in position the soldering` devices and presser-rods are alf lowed to descend, the latter holding the caps steadily in place. About two revolutions of the soldering-irons have been found suflicient to complete the operation. The caps having been soldered on, the soldering devices and presser-rods are again raised and the cans slid from under and a second series made ready.

The operating-edge of the soldering-iron is provided with slots p, the object being to prevent or obviate the presence of a completely circular edge, which has been found objectionable. The break in the edge allowing the solder to flow both inside and outside of the iron, a more perfect joint is eifected than it' the edge be a continuous circle. A single slot is, however, all that is necessary, although two are here shown.

The soldering-iron is made of copper, this metal having been found to be best adapted for the purpose.

Having described our invention, we claim as new and wish to secure by Letters Patent of the United States- 1. In a can-capping machine, the main framing-irons B and slotted bar F, carrying the series of revoluhle soldering-irons E, vertically and transversely adjustable, and provided with hollour shafts D, pulleys d, and Weighted presser-rods m, combined with a rotary driving shaft or shafts, gas-pipe branches n', and table or tray for receiving the cans to be capped, substantially as set forth.

2. The shaft D and the sleeve Gr, adjustable thereon and secured thereto by means of the screw h, and provided with the ange or collar e, having the screws 7c, combined with the slotted hollow cylindrical soldering-iron E, litting over the said sleeve and vertically adjustable thereon, substantially as set forth.

In testimony whereof' we hereto subscribe our names in the presence of two witnesses.

JOSEPH ADAMS. EDWARD RENNEBURG.
